You could ask my friend Linda at Prairie Flower Farm. They have chickens...and new chick babies that just hatched not too long ago. I think she seperates the momma and chicks from the rest of the flock for a time. Here's her blog http://prairieflowerfarm.blogspot.com/

We always just leave mama and the chicks with the rest of the hens. We have never had one die because of the other hens or rooster and we didn't have to worry about acclimating the chicks with the adults once it is time to put the in the same pen (or reaquainting mama with her flock mates if separating them for a bit of time) Chickens can be quite mean when new chickens come around but we never had a problem when they all stayed in the same pen from the time of hatching forward. Good luck with your chickie endeavor!!

Congrats!! We put a separate penned off area in the coop so Mama and chicks could be with the other girls but Mama didn't have to be so stressed out over protecting those little chicks. The other ladies were quite nosey and loved to check in on everyone. When you do finally release them to be with the others there's a whole lot of pecking for a little while, but eventually it all calms down. We would make sure to hold the chicks often, one at a time so as not to make Mama too upset, but we wanted them to be friendly. Our last batch we hatched two. One is the bratiest of girls you've ever met and the other is sweet as pie......I say one takes after papa and one after mama. :-) Good luck!

Yay!! How exciting! I would suggest letting mama raise her baby chicks and separating them in a safe place away from the others- she knows best how to keep them warm, teach them how to eat, drink, scratch, and all the complex calls and language of chicken talk. It was so cute watching our broody hen with her babies- sometimes I would dice up special treats like blueberries for the chicks and she would go crazy clucking to them to show that the treats were the extra special good stuff. Then once they got a few weeks older they would always be partial to those treats she told them were the best over others. Just watch over them to be sure they are all ok and that they have adequate chick feed and access to water.
